It depends on the distance away from the hole. Personally, I like to take it out when I start to get into the 20-25 foot range. I can see more of the hole, which in return makes the hole appear bigger. If I’m farther away I simply just try to get it close to the hole for an easy tap in. A lot of students have started to use this approach and have had success. I’ve seen so many people leave the flag in and have it hurt them. I’ve also heard where it has helped many as well. It comes down to basically personal preference. If it improves the golfers confidence I am always on board!!
